The same reference characters indicate the same-parts in all of the figures. i

In the drawing, |2-|2 designates the pulley stiles of a double hung window frame, each stile having a vertical parting bead-receiving groove l3. The lower ends of the grooves are closed by the top surfaces of the sill member M of the frame, so that the lower ends of parting beads l5 inserted in the grooves are seated on the sill.

The upper portion of the frame formed by the top header i6 is provided with means for releasably confining the upper end portions of the parting beads l5, said upper ends being engageable with said means by manipulation of the beads, as described later. Said confining means may include faces ll of notches formed in the usual finish header 8 attached to the top header l6, said faces being spaced from the grooves sufficiently to bear on the exposed outer faces of the parting beads, as shown by Figure 2. If desired said confining means may be provided by the end portions of the-lower face IQ of a horizontal top bead 20, (Figure 8) said top bead being attached to the top header Hi.

The structure includes immovable stops 22 rigidly attached to the lower portions of the frame. Said stops have abutment surfaces 2| projecting upwardly from the sill, and facing the lower ends of the-grooves 3, in position'to abut the lower portions of the outer sides of the parting beads I 5, 10

when only the lower ends of the beads areinserted in the grooves, and the beads are inclined as shown by Figure'9. Said stops are preferably attached to the sill, and may be of any suitable form. Preferably each stop 22 is a disk of any 15 suitable material, (sole leather being a suitable material) secured by a nail or screw to the sill, as shown by Figures 1,2, 3, and 9. Figures 4 and 5 show the stop 22 as a metal plate having a thicker end onwhich the abutment surface 2| is formed, the opposite end being reduced to a thin edge. Figure 6 shows the stop 22 as the circular head of a screw, a portion of the periphery of the head constituting the abutment surface 2 I. The threaded shank of the screw shown by Figure 6 permits a suflicient upward adjustment of the stop 22, to enable it to confine the lower end of a parting bead which may have been out too short. Figure? shows the stop 22 as a staple driven into the sill, one side of the staple constituting the abutment surface 2|.-

The said stops are preferably in practice secured to the frame at the factory where the frame is made, and the parting beads may subsequently be secured to the frame by a carpenter. The operation of securing the beads may be asnext described. a

Before securing the parting beads the carpenter hangs the upper sash in the frame and lowers it, as indicated by Figure9, until its meeting rail 23 rests on the stop 22. sion or. projection 24 formed on this meeting rail to enter a corresponding recess in the meeting rail of the lower sash, (not shown), is cut away to form a recess or groove 25, one face of which The usual lateral extenguides the lower end of the parting bead into the where the frame is made, and the parting beads are applied by a carpenter. Before the application of the parting beads to the frame the carpenter applies each parting bead by inserting its lower end in a recess 25, swinging the bead to its final position in the groove [3 and then securing the upper end, as by applying the finish header I8 to the top header it so that the finish header face I! confines the upper end of the bead.

When it becomes necessary to replace an originally applied parting bead which has become inoperative, by a new bead, the finish header I8 which was applied by the carpenter remains in place, and the lower end of the new bead is inserted in the recess and its upper end is placed in contact with the under side of the finish header I8, the bead being at first inclined outward from the groove IS. The upper end of the bead is then forced along the under side of the finish header toward the groove I3 until the upper end of the bead springs into the finish header notch and against the abutment face H, the bead being H slightly flexed, as shown by dotted lines in Figure 2, while being forced into the groove, until its v Figure 2.

upper end passes beyond the face I'I, whereupon the bead automatically straightens and its upper end abuts said face, as shown by full lines in After the application of the parting bead the lower sash is hung as usual.

When the top header is provided with the horizontal top bead 29, the manipulation of the parting bead by the operator consists in swinging the bead inwardly after its lower end abuts the sill, until the upper end is in sufficiently firm frictional engagement with the face I9 of the tophead 2!] to prevent the bead from coming out of the groove, no spring fiexure of the bead being required.

It will be seen that after the parting beads have been secured as described there is no liability of the accidental release of either bead, and that the beads and sashes may be easily removed and replaced.

It is obvious that the frame may be provided with means other than the finish header I8, or the top head 20, for securing the upper ends of the parting beads.

The frame characterized by the fixed stops 22 permits the securing of the parting beads without the use of movable fasteners, and eliminates the use of brads driven through the parting beads, into the sill or the stile. Such brads are liable to split the beads. The fixed fasteners allow the parting beads to be made with plain flat surfaces without shoulders, grooves, notches and inclines, and the frame to be made without depressions and recesses in the sill I4.

It is well known that the lower portions of the parting beads of a double hung window are not protected from the weather by the upper sash, and are therefore liable to be caused by warpage to spring outward from the grooves. This liability is not always prevented by brads driven into the exposed portions of the beads because, as above stated, the brads are liable to split the beads and lose their hold thereon. Moreover, the brads are liable to be pulled out by the warping of the lower portions of the beads.

There being no movable securing units there is little or no liability of the completion of a window without suitably fastening the parting beads, such as is sometimes caused by carelessness of workmen.

The application of paint to the sill I4, and to the immovable stops 22 does not affect the usefulness of the stops, the same remaining in place after being attached at the factory. Parting beads have to be removed occasionally to permit repairs, and have to be renewed when injured or broken. The fasteners 22 are improved by paint- 5 ing and permit the convenient renewal of the parting beads, and the use of parting beads of extremely simple form, extending continuously from the top beads to the sill.

It will be seen that the fixed stops 22 may be 10 rigidly attached to any suitable portions of the frame, and are formed and arranged to be engaged with the lower end portions of the parting beads I5 by a downward endwise movement of the beadsto confine said lower end portions in 15 the grooves it. It will also be seen that the stops are wholly out of contact with the sides of the parting beads which bear on and project from the grooves in the sides of the frame, so that the beads are freely engageable with the stops 2 when the beads are inclined relatively to the sides of the frame.

It will also be seen that each embodiment of the means associated with the top header I6 for confining the upper end portions of the parting 25 beadsin the upper portions of the grooves I3 is caused to perform its function by lateral movements of the beads without bodily endwise move-' ment thereof, the means shown by Figures 1 and 2 being embodied in the shoulder I I formed on the finish header I8, and the means shown by Figure 8 being embodied in the top bead Zll attached to the finish header and having a horizontal bottom face arranged to contact with the upper ends of the parting beads and frictionally confine said upper ends in the grooves.

Referring to Figures 1 and 2, it will be seen that the arrangement is such that the parting beads are confined by first engaging their lower ends with the fixed stops by downward endwise movement of the beads, then flexing the parting beads as indicated by dotted lines in Figure 2 to slightly lower their upper ends, and finally moving the beads laterally into the grooves to cause their upper ends to spring behind and engage the shoulder N, there being no bodily endwise movement of the parting beads.

Referring to Figure 8, it will be seen that the arrangement is such that the parting beads are confined by first engaging their lower ends with the fixed stops, and then swinging the parting beads laterally inward until their upper ends are frictionally confined by the top bead 20, there being no bodily endwise movement of the parting beads.

Provision is therefore made for easily securing the elongated parting beads by exerting a minimum degree of force thereon which is much less than would be necessary if the beads required endwise bodily movement in the grooves, and for removing the parting beads with corresponding ease.
